Biocompatible Multifunctional Polymeric Material for Mineralized Tissue Adhesion

Advanced Healthcare Materials, EarlyView.
A multifunctional thiol‐ene resin system is developed that provides a strong adhesive interface with dentin while maintaining biocompatibility with dental pulp cells. The addition of an acidic monomer to a triacrylate‐trithiol‐based resin achieves over 10 MPa shear bond strength by reinforcing the hybrid interface.

Sharp Curvature of Premolar Resulting in External Apical Root Resorption of the Neighbouring Molar

Case Reports in Dentistry, 2011
This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

Advanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Risk prediction model of impacted supernumerary tooth-associated root resorption in children based on cone-beam computed tomography analysis: a case control study

BMC Oral Health
Background External surface resorption is pressure-induced resorption and occurs on the external surface of the root, pressure exerted by impacted teeth, is common causes of external surface resorption.

Human life history evolution explains dissociation between the timing of tooth eruption and peak rates of root growth.

PLoS ONE, 2013
We explored the relationship between growth in tooth root length and the modern human extended period of childhood. Tooth roots provide support to counter chewing forces and so it is advantageous to grow roots quickly to allow teeth to erupt into ...

Molecular regulatory mechanism of tooth root development [PDF]

International Journal of Oral Science, 2012
The root is crucial for the physiological function of the tooth, and a healthy root allows an artificial crown to function as required clinically. Tooth crown development has been studied intensively during the last few decades, but root development remains not well understood.

A sweet tooth as the root cause of cardiac arrest [PDF]

Canadian Journal of Cardiology, 2009
A 71-year-old woman was admitted with hypotension and bradycardia. An electrocardiogram showed flattened T waves and increased U wave prominence, resulting in a long QT(U) syndrome. Her initial serum potassium level was 1.6 mmol/L (all other electrolytes, including magnesium, were normal).

Could the pulp be preserved in tooth with root resorption caused by embedded tooth?

Journal of Dental Sciences, 2023
At present, there are no recognized guidelines or consensus for the treatment strategy of the asymptomatic tooth with external root resorption caused by an embedded tooth (et-ERR). Most clinicians would like prophylactic or concomitant root canal therapy (RCT) along with the extraction of the embedded tooth.
